Custom Content Shortcode <= 4.0.1 - Authenticated Stored Cross-Site Scripting

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2021-24826
CVSS Medium (5.4)
Publicly Published February 2, 2022
Last Updated January 22, 2024
Researcher Francesco Carlucci
Description

The Custom Content Shortcode WordPress plugin before 4.0.2 does not escape custom fields before outputting them, which could allow Contributor+ (v < 4.0.1) or Admin+ (v < 4.0.2) users to perform Cross-Site Scripting attacks even when the unfiltered_html is disallowed. Please note that such attack is still possible by admin+ in single site blogs by default (but won't be when the unfiltered_html is disallowed)
